The centaurs of Greek mythology are creatures that are part human and part horse. They are usually portrayed with the torso and head of a human, and the body of a horse. Centaurs are the followers of the wine god Dionysus and are well known for drunkenness and carrying off helpless young maidens.
If both healthy parents carry the same altered recessive. gene, then each child they have has a 25% (1 in 4) risk of. inheriting the altered gene from both parents and therefore. being affected. For each child, regardless of their sex, the. risk is the same = 25%. Children of couples who are both carriers of the same. altered recessive gene have a 50% (1 in 2) chance of. inheriting one copy of the altered gene from one of their. parents. If this happens, they are healthy carriers. themselves.
Genes are found on the chromosomes in a cell. The combinations of genes for each trait occur by chance. When one gene in a pair is stronger than the other gene, the trait of the weaker gene is masked, or hidden. The stronger gene is the dominant gene, and the gene that is masked is the recessive gene.Dominant genes are written as capital letters and recessive genes are written as lowercase letters. If both genes in a gene pair are the same, the trait is said to be homozygous, or pure.enes are found on the chromosomes in a cell. The combinations of genes for each trait occur by chance. When one gene in a pair is stronger than the other gene, the trait of the weaker gene is masked, or hidden. The stronger gene is the dominant gene, and the gene that is masked is the recessive gene.
